From Boston Properties announcement: "Construction of foundations is well underway at the site and the Company intends to complete them to facilitate a restart of construction when it deems it propitious to do so."

A week has gone by, and they are continuing to work on the foundation, which suggests they are locked in on the current architectural plans. So they expect to retain the property, as any other developer would want their own design, and changing the foundation could be quite expensive.

I'm betting it's a long wait before BP see it as "propitious."
